1 l desianate specifically to the drawing ior a Mailed: deacription oi,my invention; numeral in its underside for apurpose hereinafterdescribed, A plurality of slots ll extend upwardly verse: wall membersit. wall members are assembled on'the longitudinal wall member 1:, theportions II are bent parallel to the remainderoii the longitudinal wallmember I! and retain the transverse wall members ll loosely therein andnormally inclined' slightly to the vertical.

The transverse. wallmembers II have slots il extendingirom the topthereof and slots 2i ex:

tending from the bottom thereof. The up r slots ll receive the upperportion oi the longitudinal wall member it between the slots i1 and theslideway II and the lower slots II receive the shoulders 22 formed atthe bottom-oi the slots llin the longitudinal wall member l3.

I A handle or leverage device, generally indicated at a, slideslongitudinally on the slideway II. The handle 28 is provided with a pairoiinturned lower lugs and an upper central 1| between which is icrmed ana which receives the slideway Ii. The

centralbody portion Ilfoji the handle Ifdoes not extendover the inturnedlugs 24 so that the handle 23 is capable of being moved lengthwise onslideway II or angularly thereto as shown 15 ,3. @The: innerfanduh o theinturned lugs 28 engage the slideway 23 and preferably the notches l ltherein, to prevent lengthwise movement of the handle 23 when it isrotatedangularly. Alter the handle II is assembled on the slideway II,the ends 0! the slideway are bent as shown at 21 to prevent the j handleNfirom being removed from the slideway II. It' will be noted that theslideway ii extends above a lip II of the ice pan Ii.

In operation, the ice pan is filled with water approximately to thelevel '2! shownin Fig. 2

and the removable grid i2 is placed in the ice pan to form two rows ofcellsji which iorm ice cubes 3! when the water is frozen. After the t wt uc ur i epre r b rwu water is irozen, the handle 23 is movedlongilongitudinalfwall member iland a plurality'oi u'pright transversewall members id. The longitudinally along the slideway ii to theleft-hand extremity thereof and the handle 23 is-then moved angularlyand engages the lip 28 or the ice pan II to lift the grid l2'and thefrozen ice cubes 32 from the ice pan H. The grid 12 is then preferablyremoved and the handle 23 is slid lengthwise to the right-hand extremityof the grid until it engages the first notch l'6. The handle 23 is thenagain rotated angularly as shown in Fig. 6 until the bottom of the lugs24 partition means and being mounted for'independent angular movementwith respect tosaid longitudinal partition means, a slideway formed atthe topof the longitudinal partition means,

' nally on said slideway and then angularly with respect to saidslidewayto impart ice dislodging engages a rounded portion 30 at the top of thetransverse grid walls l4. Further movement ofthe handle member 23rotates the transverse wall '5 members. ll angularly and breaks thefirst set .ofice cubes "from the gridtstructure II, the 1 movement ofthe transverse wall members ll being limited by theslots l1, 'ljhehandle member 23 is then moved to the left untilit'engag's' the n'e'xtnotch l6 and the operation is repeated; and so on until theirequirednumber of ice cubes are removed by two's from the grid IL If it isonlydesired to remove a small number of ice cubes from the grid structure,it is obvious that this 1 7 may be accomplished without disturbingthere- 1 mainingvgice cubes and thereafter the-grid I2 may be replaced in.the pan II and, if. desired, the cells, Jiwhich have had the' ice cubesremoved therefrom may be refilled with water for freezing. a I 7 v IFrom the foregoing, it will be apparent thatI have provided a gridstructure in which the leverage means for removing the grid from-the icepan and; for thereafter imparting ice dislodging movement to the icecubes is attached to the grid 7 structure and wherein pairs of ice cubesmaybe removed from the grid structure without disturbing the remainingice cubes'thereon. It will also be apparent that the grid structurewhich I have provided is capable or being formedof relativelyinexpensive stamped aluminum, parts and is readily assembled.

While I have shownmy invention in but one and leverage means arranged tomove longitudimovement to pieces of ice between adjacent transversewalls on both sides of said longitudinal partition means withoutdisturbing the remainder of the ice in the grid.

4. The combination claimed in claim 3 wherein theileverage means-whenmoved angularly enages only onexof said transverse walls to move itrelative to said longitudinal partition means.

5. In liquid congealing apparatus, the combifor forming separate piecesof ice, said grid embodying a plurality of transversepartitions 'spacedlongitudinally of" the pan," and means attached to 'and,, Qv b1e firstlongitudinally of the grid and then 'angularly thereto todislodge 'the'pieces of ice from" between adjacent transverse partitions withoutdisturbing'the remaining W pieces of ice therein;fsaidfrriearis alsobeing adapted to remove the gridwith the icetherein from the pa'n; a M V'6. In'liquid congealing apparatus, the combination i of an ice bath; aremovable grid therein for dividing'the icepan into a plurality ofcellsfor forming separate'pieces of ice, said grid enibodying' a'longitudinalpartition means; and a plurality of transverse partition wallsextendingroutwardly from both sides of said-iongitudinal partition means, saidtransverse 'partitionwalls being angularly movable with respect-to andform, it will be obvious tothose skilledin the art that'it is not solimited, but is susceptible of I various changes and modificationswithout departing. from' the spirit thereof, and I desire, therefore,that only such limitations shall'be placed thereupon as arespeciflcallyset forth in the appended claims. e v ",WhatIclaimis: 4
